IPC: G03G15/01
Filed: 1998-02-05
Abstract: PROBLEM TO BE SOLVED: To execute recording on both sides of recording paper at a device having a means executing development with developer whose toner wt.% is set to be 5-35% by forming a conductive layer and a dielectric layer on both sides of the recording paper and providing a part where the conductive layer is exposed at the end part of both sides of the recording paper for taking out a magnetic pole from both conductive layers. SOLUTION: An upper face conductive body layer 102 and a lower face conductive body layer 104 are formed on both sides of the recording medium base material 101 of the recording paper, and an upper face dielectric body layer 103 and a lower face dielectric body layer 105 are respectively formed on the surface. The conductive body layers 102 and 104 are electrically exposed at both end parts of the recording paper, and function as the magnetic pole. Ions reaching the recording paper are electrified on the upper face dielectric body layer 103, and an electrostatic latent image is formed. The basic potential of the recording paper is secured by being brought into contact with the upper face conductive body layer 102 provided at both end parts of the recording paper on the side of a recording face and electrically exposed.  Thus, the formation and development of the electrostatic latent image are executed on both sides, so that the recording on both side of the recording paper is made possible by inverting and carrying the recording paper by an inversion mechanism.

Filed: 1991-02-19
Abstract: PURPOSE:To form a uniform epitaxial layer of the first and second materials on a substrate by dipping the substrate in a molten first material, dipping a sheet of the second material in the molten material parallel to the substrate and dissolving the sheet in the molten material. CONSTITUTION:A substrate 11 and a sheet 12 (e.g. graphite sheet) of the second material are held by a holder 13 so that the substrate 11 and sheet 12 are held parallel to or slightly inclined to each other by fixing to a rod 14. Meanwhile, the molten first material 16 (of Si, etc.) is placed in a crucible 15. The rod 14 is then lowered to dip the substrate 11 and sheet 12 in the molten material 16, hence the sheet 12 is dissolved in the molten material 16, and an epitaxial layer of the compd. (e.g. SiC) of the first and second materials is formed on the surface of the substrate 11. Since the sheet 12 is thus dissolved, the concn. of the second material is made uniform on the substrate 11 surface, and the materials are uniformly supplied.

Title: Still picture telephone device
Inventor: FUKUZAKI KAZUHIRO
IPC: H04N7/14
Filed: 1988-02-03
Abstract: PURPOSE:To shorten the transmission time of still picture data and also to exactly detect a transmission request signal by changing the transmission request signal to a signal easy to discriminate from an ordinary voice. CONSTITUTION:Two kinds of different single tons are successively transmitted as the transmission request signal by a double single-tone sending-out part 16 and it is detected by a double single-tone detection part 15 at a reception side. Thus, a time necessary to detect is shortened, since it is easier to discriminate from an ordinary voice rather than the transmission request signal of only a conventional single tone. When it is not correctly detected by the mixture of the ordinary voice, since a response signal is not returned, the transmission request signal is sent out again after the certain lapse of time and it is repeated till three times. Thus, a sure transmission can be attained.
